Abstract

Interoception is a complex process encompassing multiple dimensions, such as accuracy, learning and awareness. Here, we examined whether each of those dimensions relies on specialized neural regions distributed throughout the vast interoceptive network. To this end, we obtained relevant measures of cardiac interoception in healthy subjects and patients offering contrastive lesion models of neurodegeneration and focal brain damage: behavioural variant fronto-temporal dementia (bvFTD), Alzheimer's disease (AD) and fronto-insular stroke. Neural correlates of the three dimensions were examined through structural and functional resting-state imaging, and online measurements of the heart-evoked potential (HEP). The three patient groups presented deficits in interoceptive accuracy, associated with insular damage, connectivity alterations and abnormal HEP modulations. Interoceptive learning was differentially impaired in AD patients, evidencing a key role of memory networks in this skill. Interoceptive awareness results showed that bvFTD and AD patients overestimated their performance; this pattern was related to abnormalities in anterior regions and associated networks sub-serving metacognitive processes, and probably linked to well-established insight deficits in dementia. Our findings indicate how damage to specific hubs in a broad fronto-temporo-insular network differentially compromises interoceptive dimensions, and how such disturbances affect widespread connections beyond those critical hubs. This is the first study in which a multiple lesion model reveals fine-grained alterations of body sensing, offering new theoretical insights into neuroanatomical foundations of interoceptive dimensions. This article is part of the themed issue ‘Interoception beyond homeostasis: affect, cognition and mental health’.

  • Atypical interoception and high alexithymia have been observed in neurological conditions such as Frontotemporal dementia, Alzheimer's Disease, Parkinson's Disease, and Multiple Sclerosis.

    “Atypical interoception and high alexithymia have also been observed in neurological conditions with similar symptom profiles, such as Frontotemporal dementia (behavioural variant; García-Cordero et al., 2016; Salvato et al., 2018; semantic variant; Sturm and Levenson, 2011), Alzheimer’s Disease (García-Cordero et al., 2016), Parkinson’s Disease (Assogna et al., 2012; Ricciardi et al., 2016), and”

    From Atypical interoception as a common risk factor for psychopathology: A review (2021) · cites this paper as García-Cordero et al., 2016

    The Behavioural results report poorer interoceptive accuracy and awareness in behavioural-variant frontotemporal dementia and Alzheimer’s disease than in controls. The paper does not report high alexithymia in either group. The citation is attached to those two conditions, not to the separately cited Parkinson’s disease example. (LLM, conf=0.89)

  • Dysfunctional allostatic-interoception occurs in behavioural-variant frontotemporal dementia (bvFTD) patients.

    “Dysfunctional allostatic-interoception, altered processing of bodily signals in response to environmental demands, occurs in behavioural-variant frontotemporal dementia (bvFTD) patients.”
  • The transient and dynamic nature of these interoceptive deficits in people with bvFTD or AD is unclear, and previous evidence of interoceptive deficits has been largely derived from traditional, static, or behavioural measures.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
